Calculation Formula

Total Cost = (Area × Depth × Cost per R-Value × R-Value per inch) + (Area × Labor Cost per sq ft)

Where:
Area: Total area to be insulated (sq ft)
Depth: Insulation depth (inches)
Cost per R-Value: Cost per R-value unit ($)
R-Value per inch: Typically 3.8 for closed-cell and 1.7 for open-cell foam
Labor Cost per sq ft: Labor cost per square foot ($)

Spray Foam Insulation Cost Calculator Calculator Usage Guide

Learn how to use the Spray Foam Insulation Cost Calculator and understand its working principles

How to Use the Calculator

  1. Enter the total area you want to insulate in square feet (sq ft).
  2. Specify the depth of insulation you plan to install in inches.
  3. Input the cost per R-value from your supplier (typically $ per R-value).
  4. Enter the labor cost per square foot if you have an estimate or average market rate.
  5. Click the "Calculate" button to get the estimated material and labor costs.
  6. The calculator will display the total estimated cost for your project.

Understanding the Inputs

  • Area to Insulate: This is the total surface area that needs insulation. For example, if you're insulating an attic, measure the length and width of the attic and multiply to get the area.
  • Insulation Depth: The thickness of the spray foam insulation in inches. Common depths range from 1 to 4 inches depending on the climate and energy efficiency goals.
  • Cost per R-Value: The cost of the spray foam material per R-value unit. Closed-cell foam typically has an R-value of 3.8 per inch, while open-cell foam has an R-value of 1.7 per inch.
  • Labor Cost per sq ft: The cost of labor to apply the spray foam insulation per square foot. This can vary based on location and contractor rates.

Interpreting the Results

The calculator provides three key results:

  • Material Cost: The estimated cost of the spray foam insulation material based on your inputs.
  • Labor Cost: The estimated cost of labor to install the insulation.
  • Total Estimated Cost: The sum of material and labor costs, giving you a total budget estimate for your insulation project.

Important Notes

This calculator provides an estimate based on the inputs you provide. For a precise quote, it's recommended to contact insulation suppliers and contractors for exact pricing. Factors such as location, specific project requirements, and contractor rates can affect the final cost.
